Lettera Patent No. 76,260, dated March 31 1868.

I IMPROVEMENT IN MILK-STIRRERS.

TO ALL WHOM IT MAY CONOERN:

Be it knoivn that I, JOEIH. SOULE, of Georgetown, in the county of Madison, and State of'v NewYork, have invented anew and improved Milk-Stirrcr; and I do herebyl decla-re that the following is a full,'clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying` drawings, forming part of this specification, inA which- Figure 1 is a side view of my improved machine, part being broken awayto show the construction.

Figure 2 isla'perspective view of the stirrer.

Figure 3 is a detail sectional view of a modification of the bucket,

Similar letters of reference indicate corresponding parts.

My invention has for its'object to furnish au improved self-acting machine, by means of which milk may be stirred, in cheese-factoriesmnd elsewhere, tc keep the cream from rising during the night, or while said milk is standing; and it consists in the combination and arrangement of the various parts of `the machine, as hereinafter more fully described. Y v

Ais a beam, pivote'd at its middle part directly over the millnvat. B isa weight, suspended from one end of the beam A. O is a. bucket, suspended from the other end ofthe beam A, and which shall be oi' such a size that lrhen empty, may be ruised up or overbal'anced by the weight B. To one side of the bucket C is attached un arm, D, whichis connected with some tired support, as E, by a chain, F," or its equivalent, in such a way that when the bucket 'C has descended the proper distance, it will be overturned, and its contents discharged,

allowing the bucket to be again raised by the weight'. .G is asprin'g-catch, attached to some suitable support, in such a position that it may catch upon the said weighted end of the beam'A, and hold it until enough water has run into the bucket C to overcome the force of the said spring-catch G. To .the middle part of the herrin A is attached a do'wiiwalrdly-projeatingarm, H'; the. lower end ofwhich enters a slotin 'the stirre'r I, so that the said stirrer may be moved 'back 'and forth bylthe vibration of the beam A. The stirrer I consists of a longitudinal bar, il, to which are attached cross-bars, z?. i3 are pins, attae hed toand projecting from the bars c" and z2, as shown in figs. 1 and 2. The bars il .and i2 of A,the stirrerI `inn-y be solidly framed together, or they may beputeiogethcr with joints, lso`that they may be taken apart if desired, in'ord'er tobe'moreconveniently washed.

In using the machine, the' stirrer Iis thrown, into the vat upon the-topof the milk, and connected to the arm H. The waste water that flows Aaround. the vet, or asmull' stream ci' water from some other convenient source, is allowed to flow intothe bucket C. As soon as a suiicien't amount has iovfn into o verbalance the weight andovercome the force 'of the spring-catchV G, the bucket C descends, until itv'is tipped up Aby the stop; chain F, and Vthe water discharged.v 4The weight B then raises the empty bucket C, tobe again filled. The weight B, spring-catch G, and the' size of the stream of water, may be so regulated as to'operate the stirrenI v as often 'as'niay be deemed necessary. The balancing-weight B mayguif desired, be replaced by a bucket, and

the stirrer moved in both di-rections by the descent o i' a full bucket, a springatch, G, being attached to each' -eud of the beam A. The form of the 'bucket C ,is wholly immaterial, and, it' desirediit ymay .have a` valve, c,

formed in its bottom, as shown in iig. 3',v andconnected with 1some xcd suppcrtby a chain, F, or its'equivalent,

sie that, as the said'bucket descends to a certainpoint, the saidvalve may be opened, andthe water allowed toV escape.v By this construction and arrangement, the machine may beso adjusted as to Lnov'ethe s tirrcr asoi'ten or as seldom as may be desired. i i i I claim as new, and desire to secure by Letters Patente `1. The stirrer I, constructed as described, resting upon the milk to be stirred, and voperated means of the arm .H,from the beam A, having theweight B-and bucket'G, said stirrer being allewed to1rise and fall with the milk in the vat, as herein shown and described. i

2. The combination of one or more/buckets C and stop-chain or' chains F, or their equivalents-with the pivoted beam A, substantially'- as herein shown and described, and for`the purpose set forth. i

3. rlhe combination'of one or more spring-catches'G-witb' the end or ends 'ofthe pivoted beam A, substantialiy as herein shown and described, and for tbe purpose set forth.
